The Obsidian Chamber by Preston and Child is the 16th book in the Pendergast series.
Before I begin the review, I'd like to mention that this is the first book in this series that I've read and although that is almost never a good idea, I wasn't able to resist accepting this title when it was offered to me.
I absolutely loved reading this book. It was equal parts clever, suspenseful, full of unforeseeable twists and chilling and extremely interesting characters. I enjoyed the premise of the plot and I loved the fact that things were told in such a way that as a new reader to the series, I was able to get an idea about what might have happened in the earlier parts. I even got a decent idea as to how the chemistry between the characters worked up until this part. So I was really happy to get all the important background information that the authors cleverly infused without affecting the present narration.
This book had really strong characters and even though I did not fall in love with the main guy, AXL Pendergast (mainly because he wasn't the main character in this particular story) I was really drawn towards the other main characters in this book. I'm pretty sure that Diogenes might have been the crazy serial killer in the parts before this one, but in this part, I loved him as he was a completely changed man standing right on the turning point in his life. And it makes me wonder that now that I actually like the villain of the story, how could I possibly read the previous parts. Anyway, back to the character dissection, I did not much like the character of Constance. She was too "ancient" for me to feel connected to her. I did love Proctor, he is this smart, intelligent and stud guy who'd do anything to protect his people. So yeah, this is one of those books that'll make you fall in love with more than half of the characters.
The storyline was strong and so were the characters and the writing, so there was actually nothing that I, as a reader, couldn't have liked. The book started with one hell of a fast paced beginning with Proctor running around the world changing plane after plane chasing the kidnapper and I was hooked right from the start. But then a really mind-bending twist followed and I was like, "What the hell?" and then things started to get really interesting, to say the least.
The ending was a bit slow, but that could be overlooked considering that it is an ongoing series, so a mild closure for all the characters is needed. Though I would have loved to read more about proctor towards the end, considering that the book started with him. Also, a few scenes between Constance and Diogenes felt like a slog, especially when they both started talking about the ancient aristocratic stuff, but maybe that's just me.
Other than these minor issues, I loved the book, so much that I'm planning to read this entire series from beginning in the coming days. If you like reading nice suspenseful stories rich with strong characters and storylines then this book (or rather series) is for you.
